To: all `whom, it may concern.-

Be it knowntliatwe, WILLIAM J. WALKER, of St. Louis, and ALEXANDER L.BEDFORD, of Savannah, Missouri, have invented certain new and usefulImprovements in Vehicle- Wrenches, of which the following is a full,clear, and exact description, reference being had to the accompanyingdrawings, forming a part hereof. Our invention has' relation toimprovements 1n vehicle wrenches and consists in the novel arrangementand combination of parts more',

particularly described in the specification and set out in the claims;

In the drawings Figure 1 is a perspective ,view of our V completeinvention. Fig. 2 isa.

plan view of they socket showing i-nv dotted lines the various sizes ofnuts located therein;

and Fig. 3 is a vertical, crossfsectioiiv of the socket. .l In carryingout our invention the socket re ferred to is providedwith four lugssuper posed thereon, the lugs being separated by spaces at the angles orcorners of the socket. These spaces allow for the reception of a maximumsized nut, at the saine time reducing to a minimum the quantity ofmaterial compos-v ing the wrench, Ordinarily, in --case's where the bandon the hub of ,a carriagecomes in close proximity to the nut secured tothe axle,

- and which nut saidf'bandembraces, the rigid wrench as now usedcannotbe inserted within the band to grasp the nut. Especially is thistrue inA cases where 'the nuts are small as in light buggies. In compactstructures of-thisI sc rt our improved wrenchis particularlyapp'licable, as by our construction we' reduce .the circumferential sizeofthe wrench .bydispensing with the metal which ordinarily-,entersintothe corners of such wrenches. The spaces at the corners ol.'thesocket allow the corners of the maximum size nuts to pass', andthuswith a wrench composed Acf the minimum quantity of material the maximumnumberof nuts can be operated one wrench doing' the work of two ordinarywrenches under old constructions.

Referring to the drawings, 1 lrepresents the handle of the wrench oneend of 'which is providedwith three different sizedrigid vjaws 2 forreceiving'nuts of various sizes, and formed cessity.

with said handle and adjacent to said flaws is 'a hammer 3to be employedin cases of ne- 4 represents the socket of thewrench the outer surfaceof which may be of any suit- 'PATENT OFFICE- sis able shape butpreferablyl of the construction shown'in Fig. 1. fourlugs located orsuperposed upon the main portion 5 thereof.

6 represents the lugs referred-to which are separated at thecorners ofthe socket byspaces The socket is composed of 7 which' allow the cornersof the largest sized nuts to pass as shown in dotted lines Fig. 2. .Themain portion 5 of the socket has forfned on its inner walls four rightangular grooves 8 midwaybetween the four corners 9, which groovesv areadapted to receive the four corners of the smallest nut v10 as shown indotted lines Fig. 2. The four corners andthe walls at rightanglesthereto are adapted to receive the next larger nut 11 as shown indotted lilies in Fig. 2 ,Formedon the inner walls or s urfaces of eachlug 6 are'right angular grooves 12 which receive the corners of the nextlarger nut 13 also shown Ain dottedlines in Fig-2; Said `lugs areprovided with plane surfaces 14 which arel eight in numberA and whichcome .in contact with the sides of .the nut 15 shown indotted lines Fig.2. A socket constructed as above .described is applied to nuts ofvarious sizes from one side of the socket only, and

` when thus applied hexagonal as well'as square` nuts can beaccommodated. r

0f course it will be understood that hexagonal nuts will not beaccommodated snugly within the socket,gbut as.` the saine is constructedto receive nuts of various sizes the socket will grasp the nutssiivlciently for turn-- ing the same.l y

In constructing 'tlie socket a. continuous shoulder 16 is formedhavingonjeach of the four sides thereof two surfaces 17 which inelinetoward each other, and iiito'j-the right 'I angular shaped grooves 8,Aas shown in Figs. 1 and 3. These inclinations allow the nut 13 `toenter farther into the right angular shaped grooves 12 of the lugs 6 andthus enable said lugs to take betterhold of the nut.' Another object -oftheinelined surfaces is to transfer a portion 'of .the strain taken bythe, lugs to i the body portion of the socket.

'mainportion 5,V righty angular grooves 8 formed on thenner walls oflthe same, between the y 15 )corners 9, lugs 6 superposed on saidportion 5 providing spaces 7, right angular grooves l2 formed on thesaid lugs, plane surfaces 14 also formed on said lugs, a continuousshoulder 16 having' inclined surfaces I7, and ahandle for zo i sa'idsocket, substantially as'set forth.

In testi mon ynvhereof we ax oursiglmtures in the presenceof twowitnesses.
